My present invention relates to the general class of power operatedappliances for brushing, scrubbing and cleansing such commodities asfruits and vegetables, and more specifically to an improved egg cleanerand polisher of the rotary, vertical axis type, and operated by anelectric motor or other suitable source of power.

The primary object of the invention is the provision of a manuallycontrolled appliance of this character that is composed of a minimumnumber of component parts which may be manufactured with facility at lowcost of production; and the parts may be assembled with convenience toconstitute a cleaner and polisher that is simple in construction andoperation, and by means of which an egg may be cleansed and polishedwith rapidity, with a minimum expenditure of time and labor.

To this end the invention consists in certain novel features ofconstruction and combinations and arrangements of parts involving amanually depressed and resiliently supported, rotary, holder for an eggthat performs the functions of a motor-operated cleaner and polisher, ashereinafter described in detail and more particularly set forth in theappended claim.

In the accompanying drawings I have illustrated a complete example of aphysical embodiment of my invention wherein the parts are combined andarranged in accord with one mode I have devised for the practicalapplication of the principles of my invention. It will however beunderstood that changes and alterations are contemplated and may be madein these exemplifying drawings and structures, within the scope of myclaim, without departing from the principles of the invention.

Figure 1 is a view in elevation embodying my invention, the exteriorhousing or stationary shell therefor being shown in section forconvenience of illustration.

Figure 2 is a vertical sectional detail view of the depressible andspring-lifted holder and brush, together with a rotary tubular shaft andenclosing cup.

Figure 3 is a top plan view of the structure in Fig. l.

The appliance of my invention may be supported upon a table T, or otherdesired stationary object, and an electric motor M having the YlfClaim.(Cris-3.1).,

usualelectrical connections, and rotary vertical shaft S is employed foroperating the cleaner and polisher. For supporting the appliance a frameI ismounted on the table, and its integral band 2 encircles the motor,and is clamped thereon at the joint 3.

The upper end of the vertical motor shaft S is equipped with a couplingcollar or bushing B, and the bushing is rigidly clamped on the shaft asby set screws 4, while other clamp screws 5 rigidly fix the upper end ofthe bushing on the lower end of a rotary tubular shaft 6.

On the upper end of the tubular shaft an integral head I is provided anda semi-circular cup 8 is fastened in the dished face of the head byscrews 9, while the wall of the cup outwardly and upwardly flares toform a comparatively large mouth I0.

For cleansing and polishing an egg as E, the latter is placed in adepressible, spring-lifted or resiliently supported and rotary, brushingholder, and the egg is depressed by hand in the brushing holder forcleansing and polishing its lower half, and then inverted and insertedin the brushing holder for cleansing and polishing its other half.

The brushing holder, which forms a receptacle for the egg, includes astem or shank ll having a. slide bearing [2 in the head 1 of the tubularshaft 6, and the stem at its lower end is threaded in a coupling sleevel3 that is splined Within the tubular shaft. By inserting the stemthrough its bearing and the sleeve up through the open lower end of thetubular shaft, v

a screw driver may be applied to a kerf [5 of the sleeve [3, and thethreaded end of the stem may be screwed into the tubular shaft, thuscoupling the stem and the tubular shaft for rotation and permitting thebrushing holder to reciprocate vertically with relation tothe cup andthe tubular shaft.

The combined brush and holder for the egg includes a brush head I 6 thatis threaded on the upper end of the stem I I, and the hemispherical orcup shaped body I! of the brush is secured to this head as by screws l8.

For cleansing and polishing the egg while it is held stationary in thebrushing-holder, the body of the brush is equipped with tufts ofbristles I9, a pad of steel wool, or other suitable material that formsa seat for the egg. The brushing holder may be depressed against thetension of a spring 20 that is coiled about the stem II and interposedbetween the bottom of the cup 8 and the head I6 of the brushing holder,and when the cleansed and polished egg is lifted from the brushingreceptacle, the spring lifts the receptacle into position for a secondinsertion of the egg. In this manner the necessary pressure forretaining the egg by hand in its rotary brush is resiliently resisted bythe spring 20, and the egg is held in contact with the brush as itrotates for the required period of time for cleansing and polishing.

As a protection or enclosure for the motor and its connections a casingor housing 2| may be provided, that is provided with a flanged base andattached, as by screws 22 to the table or other support T.

Having thus fully described my invention, what I claim as new and desireto secure by Let-v tical rotary shaft, of a tubular shaft rigid with themotor shaft, and-a depressible coupling sleeveslidably mounted inthe'tubular shaft to revolve therewith, of a rotary depressible stemslidably mounted in the tubular shaft and coupled at one end with thesleeve, an egg brushing-holder mounted on the other end of the stem, anda compressible spring located on the stem between the holder and thetubular shaft to be compressed therebetween a cup mounted on the upperend of the shaft concentric with and surrounding the brushing holder anda housing for the tubular shaft and motor.
